Definitions

  • the present invention relates to a foldable wall system which comprises at least two in particular flat panels which are joined along a flexible folding axis by at least one film hinge.
  • the invention also relates to a collapsible container which comprises a base, two pairs of opposite side walls and a rim.
  • the invention further relates to a method for preparing said foldable wall system as well as to a method for preparing said collapsible container.
  • Collapsible containers or crates are commonly used to transport and store a variety of items. These containers, especially when used as household articles, are regularly made from injection molded plastic. Most often such collapsible containers are made from a base, a pair of side walls and a pair of end walls which are connected via simple mechanical hinges as for example disclosed in US 6,015,056. For such collapsible containers individual components have to be manufactured in separate steps and finally assembled to furnish a usable crate. The mechanical hinges have to be arranged and designed in such a way that they allow for a reliable and perfect handling of the crate when folded.
  • film hinges have already been used with collapsible crates, as for example described in DE 201 20 563 U1 or in DE 92 18 977 U1.
  • the film hinges can be made from plastic providing a container the front and side walls, the base and the hinges of which are made in one piece.
  • a one-piece container is also disclosed in EP 0 575 594 A1 comprising a base and two pairs of opposite side walls, wherein each side wall is connected to the base by means of an intermediate member. With this construction a more stable crate shall be obtained which can be folded and reused several times and which is easy to manufacture.
  • Film hinges are especially used with caps and closures for bottles or containers, in particular to alleviate the dispensing of fluids or liquids and/or to keep both parts together, so that the cap does not get lost.
  • These film hinges which usually connect the top and bottom part of a cap can be used in combination with a snap element as for example described in CH 683092 A5.
  • Such snap elements are molded to the top and bottom part of a cap and consist of several elastic subsections which may be c-, v- or o-shaped.
  • EP 0 873 944 A1 a closure with a snap hinge cap including a first part adapted to interengage with the open neck of a container and a second part forming a cap is disclosed.
  • a pair of hinge straps is used on opposite sides of an integral hinge.
  • the integral hinge which can be a film hinge, is bent either in opposite or in identical directions when the first and second parts are in fully open position.
  • a snap hinge which is integrally made of a plastic material and which can constitute a part of a closure, a deep drawn package or other plastic articles is disclosed. It is essential that the film hinges which link connecting elements to the hinge members are not parallel but diverge so that the connecting elements cover a planar or special triangular surface.
  • the connecting element is preferably joined to the hinge members by oblique film hinges.
  • film hinges are, thus, mainly adapted to the specific needs of circular-shaped caps and closures, and is not concerned with articles which have to be suited to carry loads.
  • a foldable wall system which comprises at least two, in particular flat, panels which are adapted to be aligned horizontally and which are joined along a flexible folding axis, in particular along their adjacent aligned longitudinal edges, by at least one film hinge, wherein adjacent to the film hinge, in particular between two adjacent film hinges, at least one elastic stretch band and/or spring is/are located which is joined, in particular in one piece, with the first panel at least on one of its sides and, in particular in one piece, with the second, adjacent panel at least on its opposite side, and which is separated from the film hinge at least partially, in particular in the area of the folding axis of the film hinge, whereby the elastic stretch band or spring is adapted to be unstretched or less stretched when the adjacent panels are folded, and stretched or more heavily stretched when said panels are not completely folded or are unfolded.
  • the opposite edges of a stretch band which are usually essentially parallel to the folding axis, are located spaced apart from the folding axis and the two opposite edges of the adjacent panels.
  • the edge or edge portion of a stretch band is joined to a panel at some distance from the folding axis and the film hinge in the direction perpendicular to said folding axis. The same usually applies to the opposite edge or edge portion which is joined to the adjacent panel in a similar or identical distance from the folding axis.
  • the elastic stretch band or spring is separated from the film hinge by a slit, a cut or a gap which is located within the folding axis and/or extends into both adjacent panels, in particular having essentially identical dimensions in both directions, thereby separating an edge of the stretch band from the film hinge and both panels.
  • a slit and also a gap according to the invention have a longitudinal and a lateral dimension, the gap usually having a greater lateral dimension than the slit.
  • a cut according to the invention separates a film hinge and opposite parts of adjacent panels from an adjacent stretch band leaving both in essentially close contact.
  • the length of a slit which corresponds to the distance of opposite edges of a stretch band which are essentially in parallel to the folding axis and with which the stretch band is usually joined to said adjacent panels can vary to a great extent depending, for example, on the size and weight of the panels and on the size of the film hinges.
  • a stretch band has at least three times the length of a film hinge of a foldable wall system of the invention.
  • Provisions are being made that at least one edge of the slit, cut or gap, in particular the edge adjacent to a film hinge, is arranged essentially perpendicular to the folding axis.
  • the slit or gap is rectangular in shape and/or exhibits, in particular adjacent to the film hinge, a linear edge and/or, in particular adjacent to the stretch band, an edge having the shape of an arc of a circle.
  • two or more slits, cuts or gaps are aligned essentially in parallel to each other and in particular essentially perpendicular to the folding axis, thereby confining the width of the stretch band displaced between two adjacent slits, cuts and/or gaps. It has been found to be of particular advantage to make use of two or more stretch bands along a folding axis adjacent to each other and/or in consecutive order or sequence with film hinges. Although, each stretch band can be individually shaped, at least the stretch bands along one folding line have a more or less identical or similar design and size.
  • the folding edge of the film hinge and/or the stretch band is/are displaced into the same or in particular opposite plains of adjacent panels when completely unfolded.
  • Film hinges usually comprise wall elements which are each joined to opposite walls and panels and also a folding area or folding edge between these wall elements which regularly projects from the plain of the opposite wall elements of the film hinge when completely unfolded.
  • the folding edge can be brought in plain with the surface of adjacent panels when completely unfolded by extending the width of the panel and/or shifting said wall elements of the film hinge away from said surface towards the opposite surface of the panels.
